Actually, while there is an X11 port for OS X, it's not the native
display engine. Mac OS X uses Aqua, which is completely different from

Also, while OS X did recently get full UNIX certification, its
underpinnings are based on BSD and OpenStep, which means that it's
significantly different from Linux at the driver-level.  So even if
the drivers were open-source, porting them wouldn't necessarily be an
easy thing to do.

Finally, IIRC Apple is doing most of the graphics drivers in-house. I
doubt they'd have much incentive to use their knowledge to aid a
competing OS. (Not to mention all kinds of legal tape that'd probably
prevent them from doing so even if they wanted to.)
